After upgrade to brcmsai 8.1, the sdk running environment (container) recommended with mininum memory size as below TH4/TD4(ltsw) uses 512MB TH3 used 300MB Helix4/TD2/TD3/TH/TH 256 MB Base on this requirement, adjust the default syncd share memory size and set the memory size for special ACISs in platform_env.conf file for different types of Broadcom ASICs. How I did it Add the platform_env.conf file if none of it for broadcom platform (base on platform_asic file) Add the 'SYNCD_SHM_SIZE' and set the value for ltsw(TD4/TH4) devices set to 512M at least (update the platform_env.conf) for Td2/TH2/TH devices set to 256M for TH3 set to 300M verify How to verify it verify the image with code fix Check with UT Check on lab devices On a problematic device which cannot start successfully Run with the command $ cat /proc/linux-kernel-bde Broadcom Device Enumerator (linux-kernel-bde) Module parameters: maxpayload=128 usemsi=0 dmasize=32M himem=(null) himemaddr=(null) DMA Memory (kernel): 33554432 bytes, 0 used, 33554432 free, local mmap No devices found $ docker rm -f syncd syncd $ sudo /usr/bin/syncd.sh start Cannot get Broadcom Chip Id.
